A power cord (or mains cable) is a flexible, detachable electrical cable that temporarily connects household appliances, computers, and electronic equipment to a wall outlet or power supply. Consisting of a conductor, insulation, and a plug, they safely transmit AC power, with common types including IEC C13/C14 (computers) and NEMA plugs. They connect electronic devices to a power source, allowing for easy replacement or storage. A standard cord set includes a molded plug (male), a cable, and an appliance connector (female). They are constructed with copper or aluminum conductors shielded by insulation (PVC/rubber) and a protective jacket. Grounded cords (3-prong) provide a safety path to prevent electric shocks. IEC Connectors are common globally, such as C13/C14 for computers, C15/C16 for high-heat devices (kettles), and C19/C20 for servers. Regional Plugs Varied by region (e.g., NEMA in North America, CEE 7/7 in Europe). A power cord is typically detachable and used for portable devices, whereas a power cable usually refers to a permanently installed, long-distance electrical wire. Power Cords are commonly used in computers, monitors, and data center servers, household appliances (vacuum cleaners, refrigerators), medical equipment and professional audio/video gear.
